How about this.
Maria: Saiyonara, Shadow the Hedgihoggu...
Maria in english: Adios, Shadow the Hedgehog
WHEN DID MARIA BECOME MONDO COOL?? That she had to say something cheesy like "Adios"?! She said goodbye! Both those words mean goodbye and all they had to say was what? You guessed it! "Goodbye!" But they couldn't even do that right, they went with "Adios" like the frickin Terminator!
Sooo horrible.....
No, she said in the English version "Sayonoara, Shadow". I'm pretty darn sure.
About voice acting: Well, Ryan Drummond, Sonic's old VA, has always been Sonic for me. And I loved Eggman's old voice actor...but he died (the new one is a pale imitation).
There have been phenomenal American voice actors, at least in American cartoons. Tony Jay would make a great Wizeman...although he's also dead. Darn it. But Jackle could be played by Mark Hamill. He can do crazy.
Really, its a matter of who is casting.
